Hi Florian, to be honest I have no idea of the impact on default pipeline. I know that GVN Load PRE negatively impacts peeling, loop predication, so the passes expecting that latch has a conditional branch.
So I do not plan to update the default pipeline but if there is a volunteer to play with default pipeline, all tools will be there.
